ASP.NET Ajax ServerControls
ASP.NET Ajax server controls encompass a combination of server-side and client-side code that collaborate to deliver enhanced client behavior. The following list highlights some of the commonly utilized Ajax server controls:
- ScriptManager Control
- UpdatePanel Control
- UpdateProgress Control
- Timer Control
- ScriptManagerProxy Control
ScriptManager Control
The ScriptManager control acts as a central component in ASP.NET Ajax applications. It manages the inclusion and rendering of client script files, enabling seamless integration of Ajax functionality within the web application.
UpdatePanel Control
Update panel is capable of establishing the page update function via Ajax technique. Through separating the content in the UpdatePanel, developers are able to reload only the specified elements of the webpage which are designated in the UpdatePanel by avoiding full postback. Therefore, HTTP/2 protocol brings out more tolerable use and an important optimization of network resources.

ScriptManagerProxy Control
The ScriptManagerProxy control serves as a supplementary component to the ScriptManager control. It allows for the nesting of multiple ScriptManager controls on a single page, making it possible to integrate different Ajax functionality or behavior within separate sections of the web application.
These Ajax server controls provide developers with powerful tools to enhance the interactivity and responsiveness of web applications. By utilizing these controls, developers can create dynamic and engaging user experiences that offer seamless partial-page updates, visual feedback, timed events, and flexible integration of Ajax functionality.
Conclusion
ASP.NET Ajax server controls combine server-side and client-side code to enable the creation of rich client behavior. The ScriptManager, UpdatePanel, UpdateProgress, Timer, and ScriptManagerProxy controls are among the frequently used controls that empower developers to deliver interactive and dynamic web applications.
